ASTM A193 Grade B8P & B8PA Sample MTC Certificate
Access a comprehensive, professionally formatted Material Test Certificate according to EN 10204-2004: 3.1 for ASTM A193 Grade B8P and B8PA (AISI 305 / UNS S30500). Inspect the exact documentation your QA and engineering teams will receive with every Ananka Fasteners order.
What's Inside This ASTM A193 B8P / B8PA MTC Certificate
This sample mill test certificate mirrors the rigorous QA documentation package standard for highly formable, low-work-hardening austenitic stainless steel fasteners shipped from Ananka Fasteners Pvt Ltd.
- Full Traceability: Certified with TC No.: S111/26-XX and corresponding ASTM specifications.
- Elevated Nickel Chemistry: Detailed breakdowns verifying the higher Nickel content (10.50% - 13.00%) inherent to AISI 305. This chemistry significantly reduces the work-hardening rate, making it the ideal material for severely cold-headed or spun fasteners without requiring intermediate annealing.
- Solution Treatment Verification: Confirms the material is carbide solution treated. For B8PA (Class 1A), it specifically verifies the treatment occurred in the finished condition, ensuring optimal ductility and lowest possible residual stress.
- Mechanical Properties: Comprehensive reporting of Tensile Strength (Min 515 MPa), Yield Strength (Min 205 MPa), Elongation (Min 30%), and controlled maximum Hardness (96 HRB for B8P, 90 HRB for B8PA).
- Quality Compliance: 100% visual inspection carried out and verified free from defects and radioactive contamination.

Technical FAQs — ASTM A193 Grade B8P & B8PA MTC Certificate
Why is Grade B8P / B8PA (AISI 305) chosen over Grade B8 (AISI 304)?
Grade B8P/B8PA is formulated with a higher nickel content (10.50% - 13.00%) compared to standard 304. This specific chemistry significantly decreases the rate at which the material hardens when it is cold-worked. It is the preferred choice when manufacturing fasteners that require severe cold heading, deep drawing, or spinning, as it allows for extreme deformation without cracking or requiring costly intermediate annealing stages.
What is the difference between Grade B8P and B8PA?
Grade B8P (Class 1) is carbide solution treated prior to the final forming and threading processes. Grade B8PA (Class 1A) is carbide solution treated in the finished condition. Because 305 is specifically used for heavy cold-working, performing the solution anneal on the completely finished fastener relieves all internal stresses generated during manufacturing, ensuring maximum ductility and maintaining the strict 90 HRB maximum hardness.
Are the materials verified to be free from radioactive contamination?
Yes, the MTC document strictly states that the material has been verified as free from radioactive contamination and has undergone a 100% visual inspection to ensure it is completely free from manufacturing defects before dispatch.
